Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of anchor rod support, and particularly relates to an anchor rod bin and an anchor rod drilling machine. BACKGROUND

[0002] With the continuous improvement of the intelligent degree of coal mines, the intelligent rapid tunneling technology is continuously promoted, the mine tunneling speed has been greatly improved, and the tunneling intelligent level has also been greatly improved. The anchor rod support construction is one of the longest construction procedures in the tunneling process, by adopting a large number of anchor rod drills parallel operation and partial anchor rod lag support, the influence of the anchor rod support construction on the tunneling efficiency is reduced to a certain extent. However, with the use of a large number of anchor rod drills, the contradiction between the small number of coal mine workers and the large number of operating equipment is highlighted, and the problem of a large number of equipment and a serious shortage of operators often occurs in the underground tunneling team of some coal mines.

[0003] In the existing automatic anchor rod drill, the anchor rod is generally supplemented by a single-cycle automatic anchor rod drill and a multi-cycle automatic anchor rod drill. In the two kinds of anchor rod drills, the anchor rod and other supporting materials are stored in the anchor rod bin. In order to keep the anchor rod fixed and reliable in the anchor rod bin, a U-shaped clamp or the like is often used to clamp and fix the anchor rod, and a tray or the like is used at the lower end of the anchor rod to limit the lower end, so as to prevent the anchor rod from falling out of the anchor rod bin under the influence of mechanical vibration and the like. In the process of loading the anchor rod from the anchor rod bin to the anchor box, a mechanical hand with two sets of clamping jaws is generally used to clamp and take out the anchor rod from the anchor rod bin, and then the anchor rod is clamped and moved to the anchor box axis position. After the nut at the tail of the anchor rod is aligned and engaged, the anchor box is rotated and lifted by a distance, so as to ensure that the anchor rod is reliably engaged with the anchor box. Then, the mechanical hand can retreat to avoid the operation space of the anchor box. In the above process of installing the anchor rod to the anchor box, the anchor box will cause serious rotational friction with the mechanical hand clamping jaw when the anchor rod is clamped by the mechanical hand. At the same time, the anchor rod will also cause serious axial sliding with the mechanical hand clamping jaw under the pushing of the anchor box, which will cause serious wear of the mechanical hand clamping jaw, and after a period of use, the reliability will be seriously reduced.

[0040] Referring to Figures 1 to 6 The first aspect of the embodiment shown provides an anchor rod bin, which comprises a swing assembly, a rack 3, a limiting assembly 4 and two groups of push-moving assemblies 5. The swing assembly is used to connect with the anchor rod drill body. The rack 3 comprises two groups of slide way assemblies 3.1 and a frame assembly 3.2. The two groups of slide way assemblies 3.1 are respectively arranged at two ends of the frame assembly 3.2. The slide way assemblies 3.1 are hingedly connected with the swing assembly and can move relative to the swing assembly. The two groups of push-moving assemblies 5 are respectively slidably arranged in the two groups of slide way assemblies 3.1 and can clamp the anchor rod 14. The limiting assembly 4 is connected with the push-moving assembly 5 arranged at the top of the frame assembly 3.2. The limiting assembly 4 comprises two clamping arms 4.2 and four conical rollers 4.8. The two clamping arms 4.2 are cross-hingedly connected. The clamping arm 4.2 comprises a clamping rod 4.2.1 and a clamping head 4.2.2. The four conical rollers 4.8 are divided into two groups and are symmetrically movably arranged on the two clamping heads 4.2.2. The four conical rollers 4.8 form a clamping space for clamping the anchor rod 14. The anchor rod 14 passes through the clamping space and moves upward along the extension direction of the frame assembly 3.2. The clamping space generates resistance when the anchor rod 14 moves downward along the extension direction of the frame assembly 3.2.

[0041] Specifically, the frame assembly 3.2 is welded by section bars, the slide assembly 3.1 is welded with the frame assembly 3.2 as an integral structure, the rack 3 can rotate relative to the swing assembly, and the swing assembly is used for being connected with the anchor rod drilling machine body, that is, the anchor rod bin as a whole can rotate relative to the anchor rod drilling machine body, the pushing assembly 5 can slide along the extension direction of the slide assembly 3.1 and can clamp the anchor rod 14, the movement of the anchor rod 14 is driven to change the working state of the anchor rod 14, the limiting assembly 4 is arranged on the top of the pushing assembly 5 located above, the limiting assembly 4 adopts two cross-connected clamping arms 4.2, the clamping arm 4.2 includes a clamping rod 4.2.1 and a clamping head 4.2.2, when the two clamping rods 4.2.1 rotate around the hinge and move away from each other, the two clamping heads 4.2.2 are in an open state, at this time, the anchor rod 14 can be placed between the two open clamping heads 4.2.2, when the two clamping rods 4.2.1 rotate around the hinge and move close to each other, the two clamping heads 4.2.2 are in a closed state, so as to clamp the anchor rod 14, the positioning of the anchor rod 14 in the axial direction is realized, two groups of tapered rollers 4.8, that is, four tapered rollers 4.8, are symmetrically and movably arranged on the two clamping heads 4.2.2, a clamping space for clamping the anchor rod 14 is formed between the four tapered rollers 4.8, while the anchor rod 14 is limited, the centering accuracy of the positioning of the anchor rod 14 can be ensured, at the same time, when the anchor rod 14 moves upward through the four tapered rollers 4.8, the four tapered rollers 4.8 rotate, the clamping force of the four tapered rollers 4.8 on the anchor rod 14 decreases, the friction between the anchor rod 14 and the four tapered rollers 4.8 decreases, so that the anchor rod 14 can continue to move upward, when the anchor rod 14 moves downward, since the rollers are tapered rollers 4.8, the four tapered rollers 4.8 rotate, the clamping force of the four tapered rollers 4.8 on the anchor rod 14 increases, so that the anchor rod 14 cannot continue to move downward, the one-way positioning of the anchor rod 14 is realized, without increasing the limiting structure at the bottom of the anchor rod 14, the overall structure of the anchor rod bin is simple, the layout is compact, the occupied space is small, and the overall size is relatively short, which can be greatly smaller than the length of the anchor rod 14, when matched with the anchor rod drilling machine body, the docking device can have a larger docking space in the docking process with the anchor rod 14, avoiding the problem that the docking stroke is too short due to the long structure size of the anchor rod bin in the docking process of the docking device with the anchor rod 14, thereby causing the docking failure, and the docking success rate of the anchor rod 14 is improved.

[0042] Further, referring to Figure 4As shown, the limiting assembly 4 further comprises four roller mounting seats 4.6 and four second elastic members 4.7, the four roller mounting seats 4.6 are movably arranged on the collet 4.2.2 relative to the positions of the tapered rollers 4.8, and the tapered rollers 4.8 are arranged inside the roller mounting seats 4.6; the second elastic member 4.7 is a torsion spring, one end of which is connected with the roller mounting seat 4.6, and the other end of which is connected with the collet 4.2.2. Specifically, the four roller mounting seats 4.6 are sleeved on the collet 4.2.2, and are arranged corresponding to the positions of the four tapered rollers 4.8, that is, the distance between the two opposite tapered rollers 4.8 is adjusted by the clamping arm 4.2, and the distance between the two adjacent tapered rollers 4.8 is adjusted by the roller mounting seat 4.6, and by arranging the second elastic member 4.7 between each roller mounting seat 4.6 and the collet 4.2.2, and by making the second elastic member 4.7 a torsion spring, the tapered rollers 4.8 can always be kept in a clamping state under the action of the spring force.

The hinge pin is suitable for sliding along the guide slot 4.4. Specifically, the base plate 4.1 is made of steel plate and is used to connect with the push assembly 5. The guide slot 4.4 is machined and set on the base plate 4.1. It is used to limit and guide the hinge pin, thereby achieving limit and guide of the two clamping arms 4.2, ensuring that the limit assembly 4 will not be offset or tilted, ensuring the centering accuracy of the anchor rod 14, so that the anchor rod 14 is maintained as shown in FIG.
